class MakeLine from GCE2d inherits Root from GCE2d
---Purpose : This class implements the following algorithms used
-- to create a Line from Geom2d.
-- * Create a Line parallel to another and passing
-- through a point.
-- * Create a Line passing through 2 points.
uses Pnt2d from gp,
Lin2d from gp,
Ax2d from gp,
Dir2d from gp,
Line from Geom2d,
Real from Standard
raises NotDone from StdFail
is
Create (A : Ax2d from gp) returns MakeLine;
--- Purpose :
-- Creates a line located in 2D space with the axis placement A.
-- The Location of A is the origin of the line.
Create (L : Lin2d from gp) returns MakeLine;
--- Purpose :
-- Creates a line from a non persistent line from package gp.
Create (P : Pnt2d from gp;
V : Dir2d from gp) returns MakeLine;
--- Purpose :
-- P is the origin and V is the direction of the line.
Create(Lin : Lin2d from gp;
Point : Pnt2d from gp) returns MakeLine;
---Purpose : Make a Line from Geom2d <TheLin> parallel to another
-- Lin <Lin> and passing through a Pnt <Point>.
Create(Lin : Lin2d from gp ;
Dist : Real from Standard) returns MakeLine;
---Purpose : Make a Line from Geom2d <TheLin> parallel to another
-- Lin <Lin> at a distance <Dist>.
Create(P1 : Pnt2d from gp;
P2 : Pnt2d from gp) returns MakeLine;
---Purpose : Make a Line from Geom2d <TheLin> passing through 2
-- Pnt <P1>,<P2>.
-- It returns false if <p1> and <P2> are confused.
-- Warning
-- If points P1 and P2 coincident (that is, when IsDone
-- returns false), the Status function returns gce_ConfusedPoints.
Value(me) returns Line from Geom2d
raises NotDone
is static;
---C++: return const&
---Purpose: Returns the constructed line.
-- Exceptions StdFail_NotDone if no line is constructed.
Operator(me) returns Line from Geom2d
is static;
---C++: return const&
---C++: alias "Standard_EXPORT operator Handle_Geom2d_Line() const;"

TheLine : Line from Geom2d;
--The solution from Geom2d.
